SPECIFICATION forming part of Letters Patent No. 405,011, dated June 11,1889.

Application ilecl February 28, 1889. Serial No. 301,498. (No model.)

To all whom it may concern.-

Be it known that I, ADDIsoN K. CHASE, of Nashua, in the county ofHillsborough, State of New Hampshire, have invented a certain new anduseful Improvement in Cobblers Lasts, of which the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand :o use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure lis a sideelevation of myimproved last; Fig. 2, a plan view of the same with the'5 shanks removed;v Fig. 3, a bottom plan View of one of the shankportions detached, and Figs. 4 and 5 sectional views illustratingdetails of construction.l

Like letters and Iigures of reference indizo cate corresponding parts inthe ditferent iigures of the drawings.

My invention relates to lasts which are especially adapted for use inrepairing boots and shoes; and it consists in certain novel features, ashereinafter fully set forth and claimed, the object being to produce asimpler, cheaper, and more efective device ofr this character than isnow in ordinary use.

The nature and operation of the improve- 3o ment will be readilyunderstood by all conversant with such matters from the followingexplanation- In the drawings, A represents the body of the last, and B Cthe shank portions. The body of the last is composed of metal, and

consists of two foot portions b d, facing outward in oppositeAdirections and connected by a curved central portion f. The footportion d is of smaller size than the foot b. A horizontal socket g isform ed at the rear of each foot portion, said sockets havinginwardlyconverging walls h. The shanks B C are also constructed ofmetal, and each consists of a body portion c', the bottom or face le ofwhich is curved to form the shank and heel of the last. The forward endZ of the shank-pieces has its edges beveled to t the sockets g. Avertical arm or standard m is secured to the heel portion of eachshank-piece, the outer 5o ends q of said arms being reduced orwedgeshaped. Each foot portion is provided centrally with a longitudinally-arranged vertical slot p, which extends through the footportion and into the sockets, and is adapted to receive the ends q ofthe standards fm. The body@ of the shank-piece B is constructed smallerthan the body of the shank-piece C to correspond with the foot-piece d.

In the use of my improvement ashankpiece B or C is disposed in the heelof the boot or shoe to be repaired and the corresponding foot-pieceinserted in position therein, the end l of the shank falling into thesocket g and the end q of its arm inserted in the slot p of the oppositefoot-piece. As said end is wedge-shaped, a slight blow will cause it tobind in the slot and prevent the parts from slipping while the tap isbeing attached. The sides of the body A being curved, as shown, theycan, be readily held upon the 7o knee while in use in the shoe. The footportions b d and corresponding shank-pieces being constructed ofdifferent sizes, it will readily be seen that by use of the elongatedslots p the shank-pieces can be so adjusted in the sockets as to enablethe last to be employed in shoes varying greatly in size, the last shownbeing found in practice to take the place of thirty sizes ofcobbling-lasts in ordinary use.

In Figs. 4 and 5 a modification is shown in the formation of the slot pand arm end q, the edges thereof being corrugated to prevent theshank-pieces from slipping when the sole is hammered upon. I do not,however, deem the corrugations essential, as the wedgeshaped end servesthe purpose.

Having thus explained my invention, what I claim is- A reversiblelast-body having two sole portions of different sizes facing in oppositedirections, horizontal flaring sockets in the sole portions, andlongitudinal rectangular slots extending through said body from thebottoms of said sockets, in combination with ad- 95 instable shanksadapted to fit said horizontal sockets and provided with vertical armshaving wedge-shaped ends for projecting into said rectangular slots,substantially as described.
